Hi,
I have 10 years experience in different server platforms including Windows servers.
I have a mix of experience in a large company and at this time I manage different servers like: Active Directory forest, DNS , Web servers, Exchange server, ERP Server, Endian Firewalls and I manage a virtual desktop infrastructure with terminal servers and Thin clients.
Happy to help with removing unnecessary files and make some more space but you should not remove WINSxS folder.
All the best,
Feri
